Performing A Breakdown Test; Test In Progress - Megger OTS100AF User Manual

Favourite test standards
It is important to setup favourite test standards from the standards library to avoid navigating thorough the entire
list each time you want to change to a different test. To do this navigate to the 'Tools' top level window and select
'Manage test standards'. Then move down to 'Select favourite tests' and choose only those tests which you require,
making sure you have the most recent version of each test, unless you specifically want to use an old test standard.
Tests are greyed out when selected. Simply return to the previous screens to save your selection. The screens below
illustrate this process.

Performing a breakdown test

Select the 'Home' tab window using the arrow keys and 'OK' button. This
window offers a summary of information required for a measurement. The
following image shows a typical setup with the selected standard test, the test
ID comprised of an asset number or a serial number, the type of oil, required
electrode gap, electrode shape and finally the stirrer.
When the user selects a particular standard only valid options are presented
with respect to gap setting, electrodes and stirrer options.
Navigation is simple; up and down arrow buttons move up and down the left
side of the window whilst options for each line can be scrolled through using
the 'OK' key, or information entered in the case of Test ID.

Test in progress

During a test the screen flashes red warning HV symbols to remind the user
that a high voltage test is in progress. As a safety measure, any key press will
immediately halt the test.
The electrode potential difference is displayed as it ramps up in over-sized
digits to emphasise the presence of high voltage.
Between tests there is a dwell time and possibly a stirring action. A count
down timer indicates period of dwell or stirring remaining.
